Reported by Craig Metz [PR libc/1001]. * sysdeps/arm/sys/ucontext.h (ucontext): Likewise. * sysdeps/m68k/sys/ucontext.h (ucontext): Likewise. * sysdeps/mips/sys/ucontext.h (ucontext): Likewise. * sysdeps/unix/sysv/linux/alpha/sys/ucontext.h (ucontext): Likewise. * sysdeps/unix/sysv/linux/i386/sys/ucontext.h (ucontext): Likewise * sysdeps/unix/sysv/linux/powerpc/sys/ucontext.h (ucontext): Likewise.
